Don M Colchester , VT December 31, 2016 Appliance: Maytag 30" Built-In Electric Oven Convection JJW9530DDS31 Maytag Oven Jjw9530dds31: Hinges were weak. How to replace Appliance Fastening Screw. Bought and installed new hinges. Repair took about an hour but I also cleaned all the glass inside and out on both oven doors. I had ordered extra screws as I read the old ones that hold the hinges were hard to get in as they were self taping but the screw labeled 5 next to the hinge were not the right ones. All old screws worked fine. You just need to put a little power to them to get them started. Easy repair. 9 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
